How can I show a message during game startup?

[Max mtg]

I have a few lines of code in forge.deck.io.DeckReaderBase.readAll()

Code: Select all

            try {
                final T newDeck = read(file);
                if ( null == newDeck )
                {
                    String msg =  "A deck or similiar object at " + file.getPath() + " failed to load.\nPlease submit this as a bug with the mentioned file/directory attached.";
                    // JOptionPane.showMessageDialog(null, msg);
                } else 
                    result.put(newDeck.getName(), newDeck);
            } catch (final NoSuchElementException ex) {


I would love to trace the reason why some decks failed to load, so I want to ask player to submit the file that caused the error.
However, if a pop a JOptionPane.showMessageDialog, I get another exception.

Code: Select all

Do you have any ideas on how I can show user a message?


(Way to reproduce the problem: create an empty dir in /res/decks/sealed or draft, uncomment the showMessage line)

This is also affecting other areas - user needs to confirm deck deletion if it has wrong cards there or deletion on orphaned sealed parts.
